[Paraview] [vtk-developers] vtkMultiBlockDataSet

[Jacques Papper]

Thank you, 

That will help. What I am intending to do is modify the
vtkIntegrateAttributes class so to be a vtkMultiBlockDataSetAlgorithm so
that the result of the integration are available then for each block. I
think I'm almost there but I'm now trying to understand the whole Controller
thing and how to deal with the processes....

That'd work. But it will copy other information (besides names), if any was
well.
You can explicitly get the value of vtkCompositeDataSet::NAME() key from the
input meta-data and if present copy it to the output.

if (input->GetMetaData(iblock)->Has(vtkCompositeDataSet::NAME()))
  {
 
output->GetMetaData(oblock)->GetMetaData()->Set(vtkCompositeDataSet::NAME(),
   input->GetMetaData(iblock)->Get(vtkCompositeDataSet::NAME()));
  }
